SBC Head identification

Anyone think they could ID these heads? Not seeing anything that matches them on list. Didn't have time to pull valve covers. Center bolt.

Just get the casting number off the head by the valvesprings. They haven’t really used end markings for a long time.

Sure way is a casting # they are center bolt so they are later than 86. Intake will give a few more hints.

Garbage 193 swirl ports. Interesting because ends are different then what is shown online for 193's.
